Other agronomic traits in N. tabacum expressing CeDGAT2-2 or AtDGAT1 gene, respectively. a Total protein content; b total starch content; c total soluble sugar content; d chlorophyll content; e germination rate; f leaf biomass (dry weight). WT, wild-type tobacco plant; EV, the empty-vector transgenic tobacco plant; CeDGAT2-2, the CeDGAT2-2-transgenic tobacco plant; AtDGAT1, the AtDGAT1-transgenic tobacco plant. The top fully expanded leaf from tobacco plants at floral transition stage was sampled and divided into a number of batches for different analysis. Each value represents the mean ± SE of six biological replicates. Asterisks indicate statistically significant difference compared with the control (t-test) at * P < 0.05 and ** P < 0.01, respectively
